Some advice gets repeated so often it becomes like background noise — sound without meaning.

But when 28-year-old Jamie Nash says don’t text and drive, it’s hard not to pause and listen. It’s hard not to wince when she waves her ruined stick arms and says simply, “I did this to myself.”

When people would warn her about the danger of mobile phones and driving, Jamie imagined some sort of inconvenient fender bender — maybe a bump or a bruise at worst.

“You don’t think of what could really happen. You don’t think about burning,” she said. “This is horrific. And this is for the rest of my life.”

One June evening last summer, Jamie was driving her blue PT Cruiser on a dark, two-lane road near Ennis, where she lived. Like always, she had phone in hand.

A moment of distraction was all it took. The car drifted right, the wheels left the pavement, and it was all over. A deep bar ditch sent the car rolling over and over.

And when the rolling stopped, the flames began.

“There’s a lot of it I don’t remember,” Jamie said. “I don’t remember getting burned, so that’s a blessing.”

She was burned over 70 percent of her body — virtually everywhere but her face and front torso. Her arms were burned to the bone in places. She lost four toes on her right foot. The Achilles’ tendon on that foot was burned through.

She would spend the next 61/2 months in the burn unit at Parkland Memorial Hospital — having those burns scrubbed over and over. She recently had her 28th surgery; most have been skin grafts.

She still returns to the hospital twice a week for wound care and therapy. Her gruesomely scarred arms barely function. She can’t bend them enough to scratch her nose. The only way she can eat on her own is using a fork with a two-foot handle.

She can’t hold a phone to her ear.

How much use of her arms she will ever regain remains a question. She had to move in with her parents in southeast Dallas, and her mother had to quit her job to provide all the care that Jamie needs.

All of this because of texting while driving — reading or sending some silly message that Jamie can’t even remember.

And if you’re wondering: “Yeah, it makes you mad,” said mom Donna Ricketts. Despite the moments of anger at Jamie’s foolishness, however, Donna has devoted herself to the new role of primary caregiver.

Jamie could easily be consumed with anger at herself and bitterness at her fate. But instead, she has tried to channel her emotions in positive ways.

She focuses on the gratitude she feels toward her parents and others who have shown her such love and support through the ordeal. She relishes the spiritual growth in her life. Above all, she wants to spare others from her self-induced misery.

“While I was still in the hospital, I told my dad, ‘I have something to say.’” And with her parents’ help, she formed Jamie Nash TXT L8R Ministry. She has just begun making talks to schools and church youth groups (jamienash txtl8r.com).

Her message is simple. “I tell them: Just look at me,” she said, extending those seared arms. “And for what? All those LOLs and OMGs? What does it matter? It’s ridiculous.
